ELIMINATING MECHAN'SIMI- FOR CALCULATING MACHINES.

Application led August 4, '1921. Serial No. 489,728.

To all whom t may concern.'

Be it known that I, ARTHUR' PEN'rnoosT, a subject of the King of England, residing at New York cit'y, NewYork County, New York, have invented new and useful Improvements in Eliminating Mechanism for Calculating Machines, of which the following is a specification.

The calculating machine art is replete wit-h examples of means operated by tappetsl on .the paper carriage, as the latter shifts from column to column, to setvvarious mechanisms to effective position, so that upon the succeeding operation of the machine, the normal adding function of the machine vwill be eliminated, and the same mechanism is readilyarranged to effect thev operation of other means appertinent to calculating machines.

Sometimes, as in patent to Schuppe, #1, 308,117, July 1, 1919, means operated from the main drive shaft is -employed to set to veffective position, mechanism which eliminates or modifies the normal calculating and listing operations of the machine.

One object of the present invention is the' provision of a novel controlling medium` whereby to set the operation-modifying mechanism to effective position and to release the modifying mechanism to enable its restoration to idle position,

Another object is to simplify and improve the means to automatically control the operation-modifying mechanism, whereby to minimize the danger of getting outof order,

as well as to reduce the number. of parts, and thereby decrease the expense of manufacture.

A still further object is to provide selective means to automatically control the operation-modifying mechanism of a calculating machine, so arranged that such control may be exercised when the work sheet is brought to one or another of its positions as f the paper carriage travels from column to column, the selective means being contrived to operate the modifying mechanism one or more times as desired, in any single crosstabulating travel of the carriage.

In effecting the foregoing and other objects, I utilize the customary spring drum employed to draw 'the carriage in one direcanism which controls the operation-modifymg device.

Other objects and advantages will be more tion, as a driving means to actuate the mechi fully set forth hereinafter and particularly Vales machine, showing one embodiment of my invention applied thereto Fig. 2 is a detail plan view of the control .mechanism associatedwith the spring drum or drive means, the parts Abeing in normal idle position;

Fig. 4; is a detail lan view of one form of' adjustment app loable` to the control mechanism, parts'being removed; and

Fig. 5 is a Similar view of a modiiied Jform of adjustment.

Although I have selected the "W ales machine in connection with which to illustrate this embodiment of my invention, it is`obvious that the invention is applicable to other machines as well.

The Wales mechanism is of the general type shown in U. S. patents to Wales #794,- 205, July 11, 1905,-an #797,032, August 15, 1905; McFarland #842,232, January 29, 1907, and #1,024,013, April 2e, 191e; and Pentecost ..& Fisher #1,335,794, April 6, 1920, to which reference may be had for a more complete explanation of the construction, than that which follows.

A base 965 supports side frames 967 between which are mounted from front to rear successively, the keyboard, the accumulating and the printing mechanisms.

The keys 117 of the keyboard, arranged in denominational rows, operate corresponding levers 116 to project stops 115, likewise arranlged in denominational iiles, into the pat s of their corresponding denominational adding racks 310.

The adding racks 310 are pivotally supto advance the racks towards. their corresponding denominational les of stops 115; The restraining and restoring bar 205 is carried by fingers 265m depending from an oscillatory bar 265 extending between the side frames 967. The usual lWales mechanism, not shown, operates through the bar 265 to normally retain the restraining and restoring bar 205 vpressed. against the front arms 312 to hold the adding racks 310 intheirhome posi,

tions against thetensions of their individual drive springs 383. l y

" Depressi'ng the keys 117 corresponding to the amount to be accumulated and printed, projects the appropriate stops 115 into the paths of the racks 310 corresponding denomif nationally with the digits' composing the amount. The stops 115 when projected, displace raickarresting detents 221 which normal-ly lie in the paths of the racks 310.

A counter-Su porting axle 400 extends across the machine above thel racks 310, and denominational counters 490 areindividually journaled on the axle,'eac'h counter being provided with a pinion 435 adapted to mesh with its corresponding rack 310, to

. enable the latter to turnthe counters ac- Vsa cording to the distancesy through which the racks travel in one direction. j

Means well known in the' Wales machine and not herein fully illustrated, normally supports the counter axle 400` so that the counters are disengaged from their racks.

Advancing the main. drive shaft 200 on its forward stroke in any convenient manner, against the' tension of the main restoring spring 285, operates the usual Wales mechanism, not shown, to rock the bar 265 and withdraw the restraining and restoring bar 205 from in front-of the rack-support# ing arms 312. The springs 383 advance the of the counters 490 and their racks 310 by the customary Wales mechanism, not shown. As the main drive shaft 200 approaches the end of its forward stroke in an adding operation, Iit causes the rod 303 'to trip .the counter-supporting mechanism (not shown) and thereby effect the engagement of the counters 490 with the racks 310, after the latter have completed their advance against the key-set stops 115 or the detents 221.

The main drive shaft isthen released to enable the main spring 285 to restore the parts tonormal position. Accordingly, the` rack-restraining and vrestoring bar 205, because of yits connection (not shown) with vthe main drive shaft, presses against the front arms 312 to return the racks 310 to their home positions. The advanced racks, during such restoration, turn their .counters 490 vto register thereon. the amount. corresponding to that set up on the keyboard.

Meanwhile, the counter-engaging and disenaging rod 303, under the influence of the l'n s 214, is returning idly towards its normal position, and just prior to the end of its return travel, and after the restoration of the racks 310, it operates the well known Wales linkage (notshown) to disengage the counters 490 and their pinions 435 from the racks 310.

Printing the amount set up on the keyboard is eiiected during the same operation 4 that effects the accumulation of such amount on the counters. The yrear rack-supporting arms 311 are equipped with rearwardly extending converging levers 311m connected by restoration ofthe rack bars 310, the hammer striking tiring pins 562d to drive the latter against the positioned types 561, and impress them upon. the work sheet..A The hammers 510 are reset to cocked position during the return stroke of the. main drive Shaft 20o.

Should it be desired to print. an amount. without accumulating the same on the counters 490, all that is necessary is to prevent the enga-gement of the counters 490 and their pinions 435 with the racks 310.

Heretofore, this has been accomplished by providing a air .of retaining members in the form of 10o-ks 417 depending from a cross shaft 404 journaled in the side frames 967, and normally held inactive by a spring 481. Depression of a key 419 mounted on an arm 421 fast on the cross shaft 404 turns the shaft to rock the retaining hooks 417 beneath the counter axle 400, to hold the counter axle, and consequently, the counters 490 and their pinions 435, out of engagement with the racks 310, during the forward and return strokes of the main drive shaft 200.

rlhe s ring 481 restores the retaining hooks 41 to their normal -idle positions, upon the release of the key 419.

A platen axle 2004 on which'the platen 2094 is mounted, is journaled in end frames 2010 secured to a carriage slide 2065 travelling between the rails 2067 forming a carriage bracket extending between and fastened to the side frames 967. Shifting the slide 2065 between the rails positions one or another column on the work sheet at the printing point opposite the group of denominational type-carriers 514.

The carriage and platen are held wherel adjusted vrelatively to the printing point, by the releasable engagement of the teeth 2018m of stops, with an abutment 2091l fixed on one of the carriage rails 2067, reference being directed to the patent to Pentecost & Fisher, #1,335,794, for a more complete explanation of this mechanism. The stops are preferably adjustably mounted on a toothed bar 2092b journaled in and extending between the end frames 2010 of the carriage, and a spring 385 connected to the bar 2092", yieldingly retains the active stop tooth 2018m in engagement with the abutment 20911. A finger lever 2022i connected to the bar 2092*), enables the operator to manually release the active stop tooth from the abutment byrocking the bar 2092b counterclockwise against the tension of the Spring 385. I

Line spacing` of the work sheet is automatically effected by a thrust bar 2026, the forward end of which is connected to a cross bar 302 mounted in and extending between the radius arms 323 which support the counter-engaging and disengaging bar 303.

The rear end of the thrust bar'2026 is provided with a foot 2026m lying in front of the universal line space bail 2002 carried in the depending arms 2016a whose upper ends are `provided with trunnions 2053b journaled in the end frames 2010.`

A spring 2486 presses the universal line spacing bail 2002 against the foot 2026'. A bell crank 2016, one end of which is fast on the adjacent trunnion 2053", carries fthe line space pawl 2014 -pivotally mounted thereon, the'pawl having a stud 2058t :adaptedV to Contact the free arm of the bell crank. A spring 2082d tends to hold the line spacing pawl 2014 in contact with a line space ratchet 2020 fast with the platen.

The main drive shaft 200, on its forward stroke, advances the radius arms 323 and cross bar 302, which in turn, draws the thrust bar 2026 forwardly. Spring 2486 is thus freed to cause the universal line space bail 2002 lto follow the foot 2026m of the thrust bar, to swing the supporting arms 2016a forwardly and turn the trunnion2053b in a counterclockwise direction. The `trun- The main drive shaft, on its return stroke,

forces the thrust bar 2026 rearwardly, against the advanced line space bail 2002 the spring 385 to to drive the pawl 2014 upwardly through the abovementioned train of mechanism and feed the work sheet.

Automatic tabulation of the carriage across the machine to bring successive columns to the printing point, is conveniently effected by means of a trip member 2023c pivotally mounted on an arm 2023e fast on the trunnion 20532 in combination with a spring drum 2068, and the tape 2099 (Figs. 2 and 3) one end of which tape is connected to the. spring drum and the opposite 'end of the tape to the carriage slide 2065 in the usual manner. A s ring 582 (Fig. 1) connected to one end o the trip member 2023c tends to hold the nose at the other end of the trip member in position to contact a li 2023bsecured to and depending from the ta ulating stop bar 2092*. At each operation of the drive shaft 200, thev trunnion 2053b oscillates and rocks the arm 2023"'` to wipe the nose of the trip member 2023c past the lip 2023" to thereby rock the tabulating bar 2092* and disenvage the active stop tooth 2018m from the a utment 20916. Disengagement of the tooth 2018m from the abutment, frees the carriage to the action of the spring drum2068, which draws the carriage leftwardly by means of the take 2099. Meanwhile the nose of the trip member 2023c escapes past the lip 2023", thereby enabling restore the tabulating bar 2092.b with its stop vteeth 2018m to normal position, so that as the carriage, in its leftward travel, brings the next stop tooth 2018m to the abutment, the tooth can engage the 'abutment and `detain the carriage with a new column at the printing point, until the tabulating bar 2092b is again rocked. n

' An adjustable control member 202311 determines whether or not the column tabulating mechanism or the line spacing mechanism shall be'etective, all of which is fully explained in the patent to Pentecost & Fisher, above referred to. v

The foregoingy constitutes a part of the present invention only in so far as the various mechanisms are related to and cooperate with the novel features hereinafter set forth.

It has been shown that in cross-tabulating work the operator is relieved of the necessity of manually spacing the carriagey from column to column.

In many tabulations, it is desired to print designating numbers, dates or the like, without accumulating them on the counters, and the completion of such tabulations is facilitated, and the operators mind freed from the duty of remembering to manually operate the non-add key 419, if the non-add mechanism is arranged to be automatically shifted to eective position asthe carriage brings the columns in which dates, designating numbers and the like are listed,'to the printing point.

Heretofore, this has been accomplished in some instances, b arranging tappets on the carriage which, uring the carriage travel, vare brought into contact with mechanism set by such engagement of the tappets, to an in- /efective position, so that it will not operate to shift the counters into mesh with their racks.

In other words, the mechanism for effecting the elimination of the adding operation, does not positively hold the counters against engagement with their racks, but instead, adjusts the usual counter-shifting mechanism, so that upon the operation of the machine, the mechanism will function idly,

leaving the counters inactive.

In other cases, the nonfadd or other mechanism for eliminating or modifying the usual functions of the machine, is driven diing the normal `accumulating and printing operations of a calculating machine.

As one'simple and` convenient means to accomplish the automatic control of the nonadd mechanism'from the spring drum 2068, I provide a link 1 (Figs. lf3) connected at its forward end to one of the non-add .or

. counter-retaining hooks 417, and at its rear end to the upturned end of a lever 2, pivotally mounted at 3 on -the'bracket 2011 supface of the sprin porting thespring drum. The opposite end of the lever 2, may extend over the upper drum 2068 and carries a flipper pawl or exible tappet 4, (Figs. 2 and 3)',jthe nose of which projects beyond the adjacent end of the lever. Thistappet is pivoted to the lever at 5, and a spring 6 connected to the tap et and to a stop 7 on the lever 2, normally olds the tail of the tappet against the stop 7 which arrests its -travel in one direction.

An arm 8 (best shown in Fig. 4) loosely journaled on the lhub 2068m of the spring drum, carrieis a stud or actuator 9 nearfits outer end, the stud passing: through the arm so that its projecting lower end may enter between the teethvof a recessed or star wheel 1117 xed to-turn with the s ring drum, to retain the` arm and 'stud in p ace.

-As the spring drum 2068 and star wheel 1117 turn, in feeding the pa er carriage left- Wardly, the upper end of iilie stud y9 wipes along the nose of the tappet 4 in a counterclockwise direction, (viewing Figs. 2 and 3) to actuate the lever' 2 and force the link 1 forwardly, to shift the retaining members 417 to effective position against the tension of their restoring spring 481. The actuating stud 9 is-so positioned relatively to the lever 2, that it remains in contact with the nose of the flexible tappet 4 while the carriage is in any predetermined or selected columnar position, and continues to hold the eliminating mechanism effective until the spring drum operatesI to feed the carriage to the next column, whereuponI the stud 9 escapes past the nose of the flexible tappet 4 and enables the spring 481 to restore the eliminata ing mechanism to idle position.

Adjustment of the arm' 8 and actuator'9 relatively to the spring drum or drive means 2068, to enable the operator to select the colinnn wherein the printed amounts shall not be accumulated, may be conveniently effected in the manner disclosed most clearly in Fig. 4. The arm 8 is slotted, as at 10, to embrace the hub ,2068m of the spring drum 2068,

and may be provided with a spring-pressedy the arm 8 radially outwardl against'the in` luence of. the .spring-presse plunger 11 until the lower end of the stud or actuator 9 is withdrawn from the recess in thestar wheel, after whichA the arm 8 may be rotated on the hub to another 'position and released, Where- Iupon the spring-pressed plunger 11 draws the arm radially inwardly to seat the lower end of the stud 9 in the adjacent recess in thestar wheel 1117.

Furthermore, the hub 2068nl may carry a plurality ofarms, 8 and studs 9 superposed one above the other, as shown in Fi 1, 2 and 3,to effect the setting of the elimlnating mechanism two` or more times durin'g a single cross-tabulating journey of the carriage.

.I have illustrated in Fig. 5A a simple modication of the actuator for the lever 2. Referring to said figure, the top plate of the drum 2068 may be provided with a circular row of apertures 12, in any of which may be inserted a threaded stud 18. The tappet 4 overlies theV` circular row of apertures so that as the'drum rotates, the actuating stud or studs 13 will be brought to contact with the tappet 4 and operate the lever 2.

This contrivance lends itself readily to the purpose to which it is applied in this speciication.

The peripheral contour ofthe drum 2068 is such that in drawing paper carriages of ltle ordinary length, say thirteen inches, from beginning to end of a line, the drum will turn about one and one-quarter times.

Assuming that there is provided but a single tripping stud 9, it is obvious that it may be so positioned on the drum 2068 as to engage the flipper pawl or tappet 4, when the carriage is in any of its positions.

Thus, the trip 9 may be so located as to engage the tappet 4 when the carriage has positioned the paper at the beginning of a line, as in listing check or other designating numbers not to be added, and amounts designated by such numbers, which amounts are to be added, thus- 1273V 23. 50@ 1274-`7 4:7. 85 127 5V 9. 2l

the first column of figures being non-added as indicated by the sign, and the second column being added.

Or the use of two studs 9 properly located, will operate the non-add mechanism twice in the rotation of thespring drum 2068 as the carriage travels from beginning to end of a line, as inthe following example:

Agency No. Risk No. Amounts.

2175V 14, 234V 21. 72@ 276V 18, 725V 33. 00 277 V 9, 432 7 42, 19

wherein numbers printed in the first two columns are non-added.

It will be seen at once that the passage of a trip 9 past the tappet 4 as the spring drum shifts the paper carriage from column to column will merely operate the non-add mechanism idly, and as soon as the trip releases the tappet, the spring 481 retracts the non-add mechanism to ineliective position, and that it is only when the trip 9 remains in contact with the tappet 4 while the paper carriage is at rest that the non-add mechanism is retained effective.

With longer carriages designed to accommodate sheets of greater width, the spring drum may be equipped with a larger number of trips 9.

' When the form of trip illustrated in Figure 5 is used, the removal of all trips entirely prevents the possibility of eecting an operation of the non-add mechanism automatically, and with either form shown, it the tripping Studs are so located as to be out of contact with the tappet 4 whenever the paper carriage is at rest in any of its columnar positions, the non-add mechanism remains idle.

Other changes may be made in the form the lever as the sprinoi and arrangement of the several. parts described without' departing from the spirit and scope of this invention.

What I claim as new, is:-

1. In a calculating machine normally 'adapted to accumulate and print amounts,

the combination with a traveling carriage; a rotatabley drive means to draw the carriage; and settable means to change the normal operation of the machine; of means directly controlled by the drive means to automatically adjust the settable means to efective positio 1 2.
